    Made for winter camping.

    Get the highest warmth-to-weight ratio of any air mattress on your next winter camping trip with the Therm-A-Rest NeoAir XTherm Sleeping Pad. This lightweight pad insulates and cushions you from the hard, frigid ground below without tacking on the weight or bulk normally found in winter-worthy sleeping pads.

    Tough nylon can handle sharp jabs from rocky campsites, while the soft, no-slip top fabric boosts comfort and keeps you from slipping off your pad when you're sleeping on uneven ground. ThermaCapture layers within the pad insulate and reflect heat back to your body to keep the cold ground from sucking away all your precious heat. The mummy shape saves valuable space in your pack and shaves down weight.

    I'm Sold

    • Familiarity: I've put it through the wringer

    I don't buy into hype when choosing my gear! I check several sources I trust when I review a product. I trust Outdoor gear lab on all their top choices except when they jumped on the North Face GTX 109's(they suck) other than that they've been spot on. After reading reviews on multiple retailers sites on some of the complaints, noisy , bad for side sleepers, uncomfortable, went flat on multi day trip. I needed to lighten gear to 20-25lbs pack I had to give up my comfort set up cause I was always carrying 35 lbs+. Upgraded tent Zpacks Duplex, Pack Gossamer Gear Gorilla & HMG Windrider 3400 on wet trips, Bag enlightened equipment revelations 20, pad you guessed it this one. I addressed complaints Noisy I can live with or have you, your girlfriend or wife wear earplugs Not good for side sleepers & uncomfortable I found deflate the pad so low that when turn on your side your hips barely don't touch the floor! This solved all the uncomfortable issue even sleeping on my back is way more comfortable now! The complaint about going flat on a multi day trip! Dude those are the risks of an air pad you take your chances or go close cell or utilize the patch kit. For weight, warth & comfort "I'M SOLD"! My Backpack weight average is now 15-20 lbs . I spent a lot of money, was it worth it? Yes I can go on butt kicking trips, high elevation & not die ! it's worth every penny! Thermarest Neoair Xtherm my body thanks you!

    It does it job!

    • Familiarity: I've put it through the wringer

    As soon as you lay on the bare pad, you will feel your body heat reflected right back to you. I've switched to hammock sleeping. I throw this pad in the hammock then my bag. I never get cold and I'm a cold nature person. It will make a little bit of crackling sound as you move around on it. You get use to it. Usually after a long hike to a camp site...I'm too tired to care.

    Best Pad I've ever Owned-Then it failed

    • Familiarity: I've put it through the wringer

    This Pad was the best I've ever owned. I have been using it with a quilt system. I had 2-3 weeks of use in the backcountry with no problems. I've slept better than I have in years. It feels very delicate, so I have used kid gloves taking care of it. And of course, nothing worse than a failed pad while in the mountains and I didn't want that. Then, last week I went out on a several day backpacking trip. Unfortunately, I discovered on the first night, it no longer held air. I was unable to identify any location where it was leaking. I got to spend several nights on the ground, not fun. I really need a 4 season pad as I backpack/camp year round. Given that, I know the that I am going to be carrying some extra weight since I need the insulation. Since this pad feels more narrow than it actually is, due to drop off at edges, I went with the large at 23 oz. After this experience I decided I didn't want to deal with this kind of disaster again, so I went with the 29 0z Sea to Summit Comfort Plus Insulated. Other than the heavier weight (I'm light enough everywhere else, so not a big deal) it is better in every way. It doesn't make a crinkling noise, it's more comfortable, it has dual air chamber system in case one fails (I WISH I HAD THIS LAST TRIP), much easier to inflate/deflate, and is significantly cheaper. I'd say I should have bought it first. If you just can't handle the weight, the thermarest is still tops, but SeatoSummit pad beats it in all other categories to me. The process for refund/credit through Backcountry was stellar. I get nearly all my gear from these guys now. They are the best. I give them 5 stars, and my 2 star rating of this product has no bearing on the service I received.

    Worth the price tag

    • Familiarity: I've put it through the wringer

    Used this for over 30 days in the backcountry and gotta say I really love it. I'm tall, 6' 2" and bought a large pad. It's warm enough for winter camping up in the boundary waters and light enough for summer backpacking trips. As for people saying it's noisy, I've never encountered the noise to be too loud to disrupt my sleep. I also love this pad because I don't slip around on it as much as on my old REI pad. It comes with a stuff sack that doubles as a pump. I have the "Compak Chair" adapter that turns this into a chair, making it a wonderful item for lounging on during less intensive trips. It's durable to last through so far 1 year of abuse. I literally have no complaints with this.

    Great buy

    • Familiarity: I've used it several times

    I love this pad. It is just as comfortable as my bed. It does make a crinkle noise but it is worth it. It is much quieter with the sleeping bag on top. The comfort is heavenly. If you move lots in the night people will know. I could feel the warmth immediately. I bought a large I am 6'2 191 lbs glad I did. Thanks backcountry!

    My first Thermarest

    • Familiarity: I've put it through the wringer

    I'm familiar with several styles of inflatable mattresses, but this is my first Thermarest. I was pleasantly surprised at the speed at which the pad filled with air, only taking a handful or two of breaths to top off. I've slept on sand, gravel, cobblestone, and snow in this pad and have always been able to find comfort and warmth. I'm 6'4" and thus far have been comfortable on the standard size, and the pack down size is extremely impressive! Definitely smaller and lighter than other pads that I've used that definitely didn't shield from cold like the Xtherm.

    My first Thermarest

    Thermarest nails it again

    • Familiarity: I've put it through the wringer

    I've used various thermarest models over the years and put them through the wringer. This pad packs down so small without sacrificing ANY R-value. In fact, it is the lightest AND warmest pad I have used.

    The inflator bag is great for keeping moisture (and in turn frost) out of the mattress in those really cold environments, but is also just super convenient and makes blowing it up easier (avoiding the light-headedness).

    Bottom line, whether you're sleeping in 70°F or -40°F, this pad will keep you comfortable, will be a staple of your kit for years.

    Thermarest nails it again

    Amazed by this pad!

    • Familiarity: I've used it several times

    Took this baby packing this first week of Oct. in the San Juan's and got snowed on. I have never been so toasty warm camping above 12,000 feet this time of year, and with so little weight! Totally worth the cash.

    The best pad that exists.

    • Familiarity: I've put it through the wringer

    This is the best overall sleeping pad that exists on the market right now. It's winter rated, has a durable 70 denier bottom, and is only 15 ounces in the regular size. The comparable summer rated bad (the x-lite) is only 3 ounces lighter and has a less durable 30 denier bottom. I use this pad for all seasons and
    I don't see any reason to get a slightly lighter summer rated pad.
    Because this pad uses strips of reflective material as insulation rather than foam, down, or synth puff, it deflates completely flat and packs down very small.
    Buy once, cry once, and buy this do it all pad from company that produces in the USA. Yes its pricey but totally worth it.

    What more could you ask for?

    • Familiarity: I've used it several times

    Light, highly packable, very warm, and comfortable (quite a bit more comfortable than the old style Thermarest IMO). What more could you ask for (besides a discount - I guess you get what you pay for)?

    I was hesitant to go with the Neoair line for a while because of its reputation of being loud/crinkly. It's a bit louder than a standard Thermarest (like the Prolite series) but it's honestly not that bad, and I'm a restless sleeper. Don't let that deter you.

    Durability remains to be seen, but I wouldn't expect any major issues, presuming you take care of it (don't throw it down on bare rocks for instance).

    Great Pad to Pack Out With

    • Familiarity: I've used it several times

    I've spent so long thinking I didn't need a pad for lightweight overnight backpacking ... So wrong.

    Best night's sleep I've had in a long time. Kept me comfortable, warm and it wasn't overly bulky to carry out.

    Excellent pad

    • Familiarity: I've put it through the wringer

    I used this pad couple of days ago on an overnight trip. The temp is about 35 degree during the night. I feel so toasty and warm throughout the night. I upgraded from the z-lite. I won't even wake up if my dog did not step on me. I would highly recommend this pad to anyone. It's light and warm and durable. My dog steps on it during the night, and I don't have a problem at all.

    Excellent pad

    Best night camping in a long time

    • Familiarity: I've used it once or twice and have initial impressions

    I took this out last weekend, I think the temp dropped to around 30F overnight but I didn't wake up until the next morning perfectly warm and comfortable. Just laying on it indoors you can feel your own body heat being reflected back after about a minute.

    Very easy to inflate with the included pump sack; I think it takes me just under 10 pumps to get it to a comfortable consistency. I'm 5'11" and about 22" at the shoulders, so I ordered the large because I heard the reg had rolloff/edge support issues for back sleepers. I was able to sleep on my back and sides without any issues.


    • Familiarity: I've used it several times

    After spending a couple nights out on the pad so far this winter, I'm pretty happy with this pad. It's quite a bit lighter, packs up smaller, and is just as warm as my previous pad. The stuff sack pump is pretty handy too since I usually need one along anyway. There is a definite crinkle noise when moving around on it but that doesn't bother me. Overall I foresee getting a lot of use out this pad.

    Is that 4 seasons sleeping pad ? Is it self inflating ?

    Is this out of stock again since James's inquiry? or have you not gotten the expected shipment from 3/23? At any rate, when will this be in stock again?

    Hey Jon,

    Unfortunately we're still waiting on our shipment from the vendor.

    Sometimes they come in on time, other times we have to wait a bit longer.

    Shoot me an email if you'd like me to notify you when they come in stock.

    Shoot me an email anytime you have questions!
